First, do research. Search the company's Web site and learn about its philosophy, clients, and services. You should also do search-engine research on the company, things like articles mentioning the CEO or a specific department.

As you research, prepare questions to bring to the interview. Demonstrating interest in the company and asking smart questions will set you apart.

Second, make a checklist of the things you will bring to the interview: copies of your resume, writing samples, clip book. Thick or thin, clip books are valued and show that you are a solid worker. During the interview, sell your skills and your know-how to a potential employer. But remember, don't be full of yourself. Be knowledgeable, friendly, and positive.

Finally, following the interview, thank-you letters are not only appreciated, they are expected. In these relatively short e-mailed or handwritten letters, reaffirm what you liked about the company and how your skills will meet the agency's needs. The competition is tough, but a little extra effort can go a long way.
